This is achieved by increasing the amount of time that you hold your breath on each attempt, while the resting time is fixed. - CO2 Tolerance table – helps a body to adapt to high carbon dioxide levels. This is achieved by decreasing the length of resting time between fixed breath-hold periods. - Wonka table – a variation of CO2 tables. Apnea timer starts after the first contraction, the rest time takes one breath. - Mix table – tables where apnea time increases and rest time decreases with each round. - Custom table – allows mixing of different approaches to create a custom training, thus generating the most effective training program. - Pranayama – a breathing technique to decrease stress in the body and relax the nervous system. ◉ APPLE HEALTH SYNCRONIZATION ◉ PERSONALIZED TRAINING WITH VARYING DIFFICULTY When you start working with the application, you set your personal record in breath holding.
